FOLDING BED.

SPECIFICATION forming part of Letters Patent No. 507,103, dated October24, 1893.

Application filed December 12, 1392. Serial No. 454,917. (No model.)

To aZZ whom it may concern:

Be it known that I, ADELBERT M. BRAINARD, of Chicago, county of Cook,and State of Illinois, have invented a new and useful Improvement inFolding Beds, of which the following is a specification.

My invention relates to what are generally known as folding-beds, inwhich the bed frame is connected to the headboard or casing in suchmanner that the frame may be folded to a vertical position or extendedhorizontally for use.

My invention consists in the construction hereinafter described andclaimed by means of which I am enabled to dispense with the usualcumbersome and expensive weights, and other complicated connections andproduce a bed of few parts which will be inexpensive and simple, and inwhich the folding operation may be easily and quickly effected.

The invention also consists in the details of construction andcombination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection through a folding bed embodying my invention, the parts being inthe position occupied when the bed is to be used. Fig. 2 is a similarview with the parts in a folded position. Fig. 3 is a section on theline 33 of Fig. 1.

Referring to the drawings, A represents a stationary frame or casin gwhich is composed as usual of two vertical side walls a, connected by ahead board a.

B represents a bed frame which is adapted to receive and support themattress, and which has its head end extended between the sides of thecasing.

D represents two tracks or guides fixed to the opposite sides of thecasing on its interior. These guides extend vertically at their frontends to form stop shoulders andithen rearward and upward in a curvedpath, and are adapted to receive and sustain two large rollers dd,mounted on opposite sides of the bed frame at its head, the arrangementbeing such that as the bed frame is moved the rollers will travel on thetracks and aiford asupport for the bed frame.

E-E represents two semi-circular grooves or slots formed in the side ofthe casing and extending forward, downward and rearward as shown. Theyare arranged to receive and guide the two rollers ee, projectinglaterally from the side of the bed frame.

Under the foregoing construction it willbe seen that when the bed frameis drawn forward from its vertical position the rollers ee will travelin the forward and downwardly extending semi-circular grooves and willcause the large rollers on the bed frame to travel up the inclinedtracks until the bed frame is in a horizontal position as shown inFig. 1. In this position the rollers ee will have reached the lower endsof the semi-circular slots and will be affordeda direct vertical supportfrom beneath, so that the weight of the bed frame will be borne by therollers.

On folding the bed the large rollers will be caused to descend thetracks, the small rollers at the same time moving forward and upward inthe semi-circular slots until the bed frame is in the vertical positionwhen the large rollers will engage the vertical stop shoulders at thefront ends of the tracks and be sustained slightly above the horizontalportion of the same, and the small rollers will be in the upper ends ofthe semi-circular slots. In this position as in the horizontal positionof the bed frame the small rollers will be supported directly frombeneath, and will sustain the weight of the frame.

In certain cases I propose to so construct the parts that when the bedframe is in a vertical folded position, the large rollers will rest uponand be supported by the horizontal portion of the tracks so that theweight of the frame will be borne jointly by the small and largerollers.

It is to be understood that while I have shown and described thesemi-circular grooves as being formed in the sides of the casing and therollers carried by the bed frame it is obvious that the parts may bereversed, that is to say the semi-circular slots or grooves may beformed in the bed frame and engaged by rollers sustained by the casing,the action in both cases being identical. It is also to be understoodthat the tracks or casing may be variously constructed, and that therollers of the bed frame to engage the same, may be replaced by otherand equivalent devices provided the operation of the parts will besubstantially as indicated above.

Having thus described my invention, what I claim is- 1. In a folding bedthe combination with the casing provided at its base with the rear- 20and provided with rollers engaging in the slots, said parts so arrangedthat the rollers will be supported vertically by the walls of the slotswhen at the ends of the same.

3. In a folding bed, the combination with the casing provided at itsbase with the upwardly and rearwardly extended tracks and above saidtracks with the slots, having horizontal seats at their upper ends ofthe frame adapted to travel at its head end on the tracks, and providedwith rollers engaging in the slots, said parts so disposed that the bedframe will be sustained wholly by the rollers when in an upright foldedposition.

In testimony whereof I hereunto set my hand, this 19th day of November,1892, in the presence of two attesting witnesses.
